Luminaires that integrate Flat Optics technology deliver glare free illumination for commercial and institutional spaces. Traditional deep cell parabolic louvered troffers eliminate glare, but provide no light to illuminate the ceiling plane or upper portions of the wall, resulting in what is known as the “cave effect”.
Edge lit flat panels and center lensed troffers provide illumination to these areas, but result in glare for the occupants. With edge lit panels, and center basket troffers, up to 24 percent of the lumen output is within the glare zone.
Luminaires with Flat Optics have only 6% of the lumens within the glare zone (60 to 90 degrees), resulting in a comfortable, glare free environment. This 6 percent effectively illuminates the ceiling plane and upper regions of the wall, eliminating the “cave effect” of parabolic troffers, while maintaining a Unified Glare Rating (UGR) of less than 19.
